I know a .458 Win can be rechambered to a .458 Lott but can a .458 Win be rechambered to the .460 G&A or the .450 Vincent that Saeed put on the reloading pages.

Thank You,

Not only can it but in many ways it would be preferred option.

Rechambering is not the problem, the problesm that can come relate to feeding and magazine lenghts.

The 450 Vincent Short would be ideal for Model 70 458 conversion.
